Re: on CALL system('command') from Fortran

I was trying to see if I can call gnuplot from fortran to make a plot.

But it seems system() is not an intrinsic that is supported in
gfortran other than when using std=gnu. Googling around, it seems
this was rejected for being added to f2003, but may be in the
future it will be added?

See c-graph.F90 for some tips on plotting (I'm still a Gnuplot newbie
mind you).

Let us know if "-fall intrinsics" works for you with std=f2003. Here's
the relevant line from section 2.2 of the Gfortran manual:

-fall-intrinsics
This option causes all intrinsic procedures (including the GNU-
specific extensions) to be accepted. This can be useful with -std=f95
to force standard-compliance but get access to the full range of
intrinsics available with gfortran. As a consequence, -Wintrinsics-std
will be ignored and no user-defined procedure with the same name as
any intrinsic will be called except when it is explicitly declared
EXTERNAL.

I don't ask as many questions as I could partly because I just don't
want anyone telling me to "RTFM". Even the most prudent among us can
find it difficult to find what they're looking for in a manual. I
learnt about f90 mode from Ian Bush in this group while battling with
g77. It would have taken me a few more weeks to make the discovery by
RTFM.

The "F" in the latter is from that frackin' brilliant TV sci-fi series
"Battlestar Galactica"
I'm off to drink toffee, prepare an ambush for the cylons - and RTFM!
